The REG710EVM-5 evaluation board is designed for both DC/DC and AC/DC (off-line) power supplies. This evaluation board is especially valuable for the development of high efficiency power supplies. It delivers a regulated output of +5 Vdc at 5 A and can accept input voltage ranges from 9.2 to 25 V, while the output voltage can be adjusted from 0 V to 5 Vdc. The four layers of the board have been designed to provide an optimal path for the high current output, ensuring thermal and electrical balance. The REG710EVM-5 uses the latest generation of a monolithic integrated power converter, the REG710, which combines state-of-the-art power conversion topology with advanced power control features.

The control block that this IC is based on implements a traditional voltage-mode (VM) control scheme. Besides, it uses an optimistic average-current-mode (ACM) where a large enough sample interval is used for the inductor current waveform. The VM control block has features that help to maximize the power conversion efficiency, such as power optimizers, optimized valley-fill, and a Dual-N compensation. By using a flexible control structure, the IC is able to maintain excellent line and load regulation, an optimized transient response, and a low output noise.

The REG710 can also provide protection against load, short-circuit, and over-temperature conditions. To enable better thermal management and increased reliability, the IC provides thermal-shutdown and thermal-warning functions. These features help to ensure proper operation during overload and catastrophic failures. Also, the control circuitry can easily be disabled for power-up testing. Additionally, the evaluation board has been provided with commonly used components for optimal performance.

The REG710EVM-5 evaluation board works by regulating the outward voltage when an input voltage is applied and AC/DC conversion takes place. Depending on the required output voltage, the user can also select whether the output voltage stays constant or can be adjustable by means of an external potentiometer. When selecting an adjustable output voltage, the output will range from 0 to the input voltage value, allowing for a wide range of application. The board is also equipped with precise remote sensing capability, output voltage falls are prevented, and line transient response is improved. Depending on the application, this evaluation board can also be used in single-output or dual-output setting.

This high efficiency power supply evaluation board can be beneficial for a range of applications requiring a reliable, DC/DC or AC/DC power supply. It is especially useful for those involved in developing power supplies with high power efficiency and excellent line regulation. Some of the potential applications include: automotive lighting systems, industrial automation systems, DC/DC power converters, and 3-phase AC/DC power supplies. The REG710EV5-5 evaluation board is an ideal solution for those looking to evaluate the performance of their power supplies without having to invest in costly and complex hardware.
